  4. 22. Transition metal dissolution from Li-ion battery cathodes

    Author : Yonas Tesfamhret; Reza Younesi; Erik J. Berg; Mark Huijben; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion battery; Lithium-ion cathode; Transition metal dissolution; Atomic Layer Deposition; Inductively coupled plasma atomic emission spectroscopy; Cathode-electrolyte interaction; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : Lithium-ion batteries (LIBs) have become reliable electrochemical energy storage systems due to their relative high energy and power density, in comparison to alternative battery chemistries. The energy density of current LIBs is limited by the average operating voltage and capacity of oxide-based cathode materials containing a variety of transition metals (TM). READ MORE
